> has already been supported in release 1.10 and Python UDTF will be supported
> in the coming release of 1.11. In release 1.10, we focused on supporting UDF
> features and did not make many optimizations in terms of performance.
> Although we have made a lot of optimizations in master, Cython can further
> greatly improve the performance of Python UDF.
